THE PERCEPTION AND UNDERSTANDING OF HEALTH PROFESSIONALS AND UNDERGRADUATE STUDENTS REGARDING AGING AND THE ELDERLY

This qualitative study was developed with 117 healthcare professionals and undergraduate students who were participants of a non-verbal communication training program in gerontology, with the objective to identify the perception and understanding of healthcare undergraduates and graduates regarding aging and the elderly. The results allowed the construction of the following categories: an evolution of life that brings a variety of experiences; natural, mysterious and with accumulated experiences; a decrease in overall happiness due to an increase in isolation; a time of valuing affection and respect; an inevitable stage including distress, prejudice, and limitations worthy of attention; a natural consequence of life; and the presence of disease and the global physiological process. Regarding perceptions of the elderly, the answers were classified as positive, negative, mixed and neutral. We considered that the understanding regarding the elderly and aging was limited and pessimist, indicating a need to become aware that one's views affect the way we relate to others.

Antiresorptive drugs (bisphosphonates), atypical fractures and rebound effect: new evidence of similitude

Background: Homeopathy is based on treatment by similitude ('like cures like') administering to sick individuals substances that cause similar symptoms in healthy individuals, employing the secondary and paradoxical action of the organism as therapeutic response. This vital or homeostatic reaction of the organism can be scientifically explained by the rebound effect of drugs, resulting in worsening of symptoms after suspension of treatment. Bisphosphonates (BPs) reduce 'typical' fractures in patients with osteoporosis, but recent studies report 'atypical' fractures of the femur after stopping the BPs, a rebound effect may be the causal mechanism. Method: Review of the literature concerning the relationship between atypical femoral fractures and antiresorptive drugs (bisphosphonates), identifying the pathogenesis of this adverse event. Results: Several studies have described multiple cases of 'atypical' low-impact subtrochanteric stress fractures or complete fractures of the femur. These fractures are often bilateral, preceded by pain in the affected thigh, may have a typical X-ray appearance, and may delayed healing. Rebound of osteoclastic activity after suspension of antiresorptive drugs is a plausible mechanism to explain this phenomenon. Conclusion: As for other classes of drugs, the rebound effect of antiresorptive drugs supports Hahnemann's similitude principle (primary action of the drugs followed by secondary and opposite action of the organism), and clarifies this 'unresolved' issue. Unfortunately, the rebound effect is little discussed among health professionals, depriving them of important knowledge ensure safe management of drugs. Homeopathy (2012) 101, 231-242.

Treatment of severe forms of paracoccidioidomycosis: is there a role for corticosteroids?

Despite their immunosuppressive effects, corticosteroids have long been used as adjunct therapy (aCST) in the treatment of infectious diseases. The rationale is that in certain infections it is necessary to decrease the exacerbated host's inflammatory response, which can otherwise result in tissue damage and organ dysfunction. In fact, a major concern in treating paracoccidioidomycosis (PCM) is the host's intense inflammatory response to Paracoccidioides brasiliensis, which can be further intensified by antifungal therapy. Depending on its localization, this immunological phenomenon may be life threatening or result in permanent sequels, as is the case for some patients with cerebral or laryngeal involvement. However, the literature on aCST in paracoccidioidomycosis treatment is scarce and as a result we present our recent experience in the management of four patients with severe PCM manifestations, i.e., cerebral paracoccidioidal granuloma, laryngeal stenosis, compressive abdominal mass, and exacerbated inflammatory response with tissue destruction. In addition to the antifungal therapy, these patients required aCST, which probably promoted their clinical improvement and/or prevented serious complications. We suggest that aCST: (a) can potentially help in the management of selected cases of severe forms of PCM, particularly when there is a risk of acute complications, and (b) that it can be used safely provided that the risk-benefit ratio is carefully weighed. Well-controlled, prospective studies of aCST in the treatment of severe cases of paracoccidioidomycosis are needed to better define its role in the management of PCM.

Infliximab-induced psoriasis during therapy for Crohn's disease

Although therapy with tumor necrosis factor-alpha inhibitors (anti-TNF) provides beneficial effects in different immune inflammatory disorders, paradoxical cases of anti-THE-induced psoriasis have increasingly been reported, mostly in the setting of rheumatologic diseases. To date, less than 50 cases of infliximab-induced psoriasis in inflammatory bowel disease patients have been described. The present report was aimed at describing two new cases of infliximab-induced psoriasis during therapy for Crohn's disease and at carrying out a review on this intriguing phenomenon.

Emoções de uma escuta musical afetam a percepção subjetiva de tempo

Este estudo verificou se emoções percebidas durante uma escuta musical influenciam a percepção temporal. Músicos e não músicos foram submetidos a tarefas de escuta de trechos musicais do repertório erudito ocidental com 20 segundos de duração cada um e tarefas de associação temporal de cada trecho ouvido a durações padrões, que variavam de 16 a 24 segundos. Os trechos musicais empregados eram representativos de uma dentre as categorias emocionais Alegria, Tristeza, Serenidade ou Medo / Raiva. Uma análise de variância mostrou que, enquanto os não músicos apresentaram subestimações temporais associadas a pelo menos um trecho musical de cada uma das categorias emocionais, os músicos subestimaram todos os trechos musicais tristes, relacionados às características de baixo arousal e valência afetiva negativa.

Estudo do Padrão Respiratório e Movimento Toracoabdominal em Valvopatia Mitral

FUNDAMENTO: pacientes com valvopatia mitral podem evoluir com congestão pulmonar, que aumenta o trabalho dos músculos respiratórios; essa sobrecarga pode alterar o padrão respiratório com predomínio do deslocamento torácico ou presença de movimentos paradoxais. OBJETIVO: a) estudar o padrão respiratório e movimento toracoabdominal (MTA) em pacientes com doença mitral b) estudar o efeito do posicionamento nos parâmetros respiratórios c) correlacionar hipertensão pulmonar com presença de incoordenação do MTA. MÉTODOS: o padrão respiratório e o MTA de pacientes com doença mitral foram avaliados por pletismografia respiratória por indutância, nas posições dorsal e sentada, durante dois minutos de respiração tranquila. Analisou-se volume corrente (Vc) e tempos respiratórios e as variáveis do MTA. RESULTADOS: de 65 pacientes incluídos, 10 foram retirados, 29 participaram do grupo estenose mitral e 26 do grupo insuficiência mitral. O Vc, a ventilação pulmonar e o fluxo inspiratório médio aumentaram significantemente na posição sentada, sem diferenças entre os grupos. O MTA manteve-se coordenado entre os grupos e as posições; no entanto, cinco pacientes na posição dorsal apresentaram incoordenação (três no grupo estenose mitral; dois no grupo insuficiência mitral) com correlação significante com valores de pressão de artéria pulmonar (r = 0,992, p = 0,007). CONCLUSÃO: o padrão respiratório e o MTA não apresentam diferenças entre pacientes com estenose ou insuficiência mitral. A posição sentada aumenta o Vc sem alterar os tempos respiratórios. A presença de incoordenação toracoabdominal na posição dorsal esteve associação à hipertensão pulmonar.

An ancient founder mutation in PROKR2 impairs human reproduction

Congenital gonadotropin-releasing hormone (GnRH) deficiency manifests as absent or incomplete sexual maturation and infertility. Although the disease exhibits marked locus and allelic heterogeneity, with the causal mutations being both rare and private, one causal mutation in the prokineticin receptor, PROKR2 L173R, appears unusually prevalent among GnRH-deficient patients of diverse geographic and ethnic origins. To track the genetic ancestry of PROKR2 L173R, haplotype mapping was performed in 22 unrelated patients with GnRH deficiency carrying L173R and their 30 first-degree relatives. The mutations age was estimated using a haplotype-decay model. Thirteen subjects were informative and in all of them the mutation was present on the same approximate to 123 kb haplotype whose population frequency is 10. Thus, PROKR2 L173R represents a founder mutation whose age is estimated at approximately 9000 years. Inheritance of PROKR2 L173R-associated GnRH deficiency was complex with highly variable penetrance among carriers, influenced by additional mutations in the other PROKR2 allele (recessive inheritance) or another gene (digenicity). The paradoxical identification of an ancient founder mutation that impairs reproduction has intriguing implications for the inheritance mechanisms of PROKR2 L173R-associated GnRH deficiency and for the relevant processes of evolutionary selection, including potential selective advantages of mutation carriers in genes affecting reproduction.

Correlations between Subjective Well-being, Dyadic Adjustment and Marital Satisfaction in Brazilian Married People

This study aimed to investigate the relationships between the constructs subjective well-being (SWB), dyadic adjustment (DA) and marital satisfaction (MS). Participants were 106 married Brazilians, of both sexes, with a mean age of 42 (+/- 11) years. Instruments used for the sociodemographic characterization and socioeconomic classification were the Subjective Wellbeing Scale (SWBS), the Dyadic Adjustment Scale (DAS) and the Marital Satisfaction Scale (MSS). Through the analysis of correlations and of stepwise multiple regression, it was verified that all the factors of the dyadic adjustment showed correlation with the marital satisfaction. The satisfaction with life (factor of the SWBS) and dyadic satisfaction (factor of the DAS), were positively and significantly correlated (r = .20; p = .04), which reveals that people who say they are satisfied with life in different domains also do so in relation to the marital experience.

Cellular interference in craniofrontonasal syndrome: males mosaic for mutations in the X-linked EFNB1 gene are more severely affected than true hemizygotes

Craniofrontonasal syndrome (CFNS), an X-linked disorder caused by loss-of-function mutations of EFNB1, exhibits a paradoxical sex reversal in phenotypic severity: females characteristically have frontonasal dysplasia, craniosynostosis and additional minor malformations, but males are usually more mildly affected with hypertelorism as the only feature. X-inactivation is proposed to explain the more severe outcome in heterozygous females, as this leads to functional mosaicism for cells with differing expression of EPHRIN-B1, generating abnormal tissue boundaries-a process that cannot occur in hemizygous males. Apparently challenging this model, males occasionally present with a more severe female-like CFNS phenotype. We hypothesized that such individuals might be mosaic for EFNB1 mutations and investigated this possibility in multiple tissue samples from six sporadically presenting males. Using denaturing high performance liquid chromatography, massively parallel sequencing and multiplex-ligation-dependent probe amplification (MLPA) to increase sensitivity above standard dideoxy sequencing, we identified mosaic mutations of EFNB1 in all cases, comprising three missense changes, two gene deletions and a novel point mutation within the 5' untranslated region (UTR). Quantification by Pyrosequencing and MLPA demonstrated levels of mutant cells between 15 and 69%. The 5' UTR variant mutates the stop codon of a small upstream open reading frame that, using a dual-luciferase reporter construct, was demonstrated to exacerbate interference with translation of the wild-type protein. These results demonstrate a more severe outcome in mosaic than in constitutionally deficient males in an X-linked dominant disorder and provide further support for the cellular interference mechanism, normally related to X-inactivation in females.

Luzes femininas: a felicidade segundo Madame du Châtelet

As luzes do Iluminismo francês consagradas por certa história da filosofia foram indubitavelmente as masculinas. As presenças de Voltaire, Rousseau e Diderot nas pesquisas e nas obras sobre o período são quase absolutas. A finalidade deste artigo é explorar as Luzes francesas, particularmente, a questão ética da felicidade, pelo olhar de uma razão tão ilustrada quanto a de Voltaire, Rousseau ou Diderot, porém de saiotes e espartilho: o pensamento de Émilie du Châtelet (1706-1749). Pouco conhecida pelo público brasileiro e menos estudada ainda pelos dix-huitièmistes locais, Madame du Châtelet, marquesa de berço, escreveu, por volta de 1746, um Discurso sobre a felicidade. O exame de algumas das teses e propostas éticas contidas nesse opúsculo é uma oportunidade instigante para se entenderem um pouco melhor não só as Luzes francesas, mas, sobretudo, a sensibilidade e as angústias das mulheres de vanguarda da França pré-revolucionária.

Cytoprotective role of heme oxygenase-1 and heme degradation derived end products in liver injury

The activation of heme oxygenase-1 (HO-1) appears to be an endogenous defensive mechanism used by cells to reduce inflammation and tissue damage in a number of injury models. HO-1, a stress-responsive enzyme that catabolizes heme into carbon monoxide (CO), biliverdin and iron, has previously been shown to protect grafts from ischemia/reperfusion and rejection. In addition, the products of the HO-catalyzed reaction, particularly CO and biliverdin/bilirubin, have been shown to exert protective effects in the liver against a number of stimuli, as in chronic hepatitis C and in transplanted liver grafts. Furthermore, the induction of HO-1 expression can protect the liver against damage caused by a number of chemical compounds. More specifically, the CO derived from HO-1-mediated heme catabolism has been shown to be involved in the regulation of inflammation; furthermore, administration of low concentrations of exogenous CO has a protective effect against inflammation. Both murine and human HO-1 deficiencies have systemic manifestations associated with iron metabolism, such as hepatic overload (with signs of a chronic hepatitis) and iron deficiency anemia (with paradoxical increased levels of ferritin). Hypoxia induces HO-1 expression in multiple rodent, bovine and monkey cell lines, but interestingly, hypoxia represses expression of the human HO-1 gene in a variety of human cell types (endothelial cells, epithelial cells, T cells). These data suggest that HO-1 and CO are promising novel therapeutic molecules for patients with inflammatory diseases. In this review, we present what is currently known regarding the role of HO-1 in liver injuries and in particular, we focus on the implications of targeted induction of HO-1 as a potential therapeutic strategy to protect the liver against chemically induced injury.

Estetica ed etica: un itinerario interpretativo, alla luce della ricerca di valori nel pensiero di Ingarden, Tischner, Levinas

The research is an itinerary from the discovery of the force of Love in the Song of Songs, where the human figure is given entirely through aesthetics, right to the agony of the other's death, where ethics, the "Severe Name of Love", is the only guard left; a journey through the contradictions of human mind, that, though aiming at Good, Beauty, Happiness, is completely immersed into the darkness of its finiteness and into evil. The consciousness leads to the creation of a world whose essential prefiguration is the Beauty; whose fundamental expression is the Good. Ethics must translate itself in responsability towards the other, in the history. This immersion into reality preserves the aesthetic and ethic dimension from the temptation of absolutizing the finite. In this work, the proximity and divergence between the aesthetic and ethic dimension is analysed, with reference to significant moments of the philosophical reflection, namely in the thought of Ingarden, Tishner and Levinas.

Ricezione e Finzione. Una teoria della lettura tra struttura e risposta estetica

Attraverso l’analisi di teorie della lettura “centripete” e “centrifughe”, tra fenomenologia, semiotica e teoria della risposta estetica, questa ricerca punta a definire la lettura come un’esperienza estetica di una variabile e plurale letterarietà, o per essere più precisi, come una relazione estetica ad una funzione nel linguaggio, che di volta in volta diviene immanente e trascendente rispetto al linguaggio, immanente nella percepibilità espressiva del segno e trascendente nella sua ristretta finzionalità o fittività, aperta alla dimensione del senso. Così, la letterarietà è vista, dal punto di vista di una teoria della lettura, come una funzione che nega o sovverte il linguaggio ordinario, inteso come contesto normale, ma anche una funzione che permette il supplemento di senso del linguaggio. Ciò rende la definizione di cosa sia letteratura e di quali testi siano considerabili come letterari come una definizione dipendente dalla lettura, ed anche mette in questione la classica dicotomia tra linguaggio standard e linguaggio deviante, di secondo grado e figurativo, comportamento che distinguerebbe la letteratura. Questi quattro saggi vorrebbero dimostrare che la lettura, come una pratica estetica, è l’espressione di una oscillazione tra una Finzione variabile nei suoi effetti ed una Ricezione, la quale è una risposta estetica controllata dal testo, ma anche una relazione estetica all’artefatto a natura verbale. Solo in questo modo può essere compresa la caratteristica paradossale della lettura, il suo stare tra una percezione passiva ed un’attiva esecuzione, tra un’attenzione aspettuale ed una comprensione intenzionale. Queste modalità si riflettono anche sulla natura dialettica della lettura, come una dialettica di apertura e chiusura, ma anche di libertà e fedeltà, risposta ad uno stimolo che può essere interpretato come una domanda, e che presenta la lettura stessa come una premessa dell’interpretazione, come momento estetico. Così una teoria della lettura dipende necessariamente da una teoria dell’arte che si presenta come funzionale, relativa più al Quando vi è arte?/Come funziona? piuttosto che al Che cosa è Arte?, che rende questo secondo problema legato al primo. Inoltre, questo Quando dell’Arte, che definisce l’opera d’arte come un’arte- all’-opera, dipende a sua volta, in un campo letterario, dalla domanda Quando vi è esperienza estetica letteraria? e dalla sue condizioni, quelle di finzione e ricezione.

Marinetti ultimo mitografo

La ricognizione delle opere composte da Filippo Tommaso Marinetti tra il 1909 e il 1912 è sostenuta da una tesi paradossale: il futurismo di Marinetti non sarebbe un'espressione della modernità, bensì una reazione anti-moderna, che dietro a una superficiale ed entusiastica adesione ad alcune parole d'ordine della seconda rivoluzione industriale nasconderebbe un pessimismo di fondo nei confronti dell'uomo e della storia. In questo senso il futurismo diventa un emblema del ritardo culturale e del gattopardismo italiano, e anticipa l’analoga operazione svolta in politica da Mussolini: dietro un’adesione formale ad alcune istanze della modernità, la preservazione dello Status Quo. Marinetti è descritto come un corpo estraneo rispetto alla cultura scientifica del Novecento: un futurista senza futuro (rarissime in Marinetti sono le proiezioni fantascientifiche). Questo aspetto è particolarmente evidente nelle opere prodotte del triennio 1908-1911, che non solo sono molto diverse dalle opere futuriste successive, ma per alcuni aspetti rappresentano una vera e propria antitesi di ciò che diventerà il futurismo letterario a partire dal 1912, con la pubblicazione del Manifesto tecnico della letteratura futurista e l'invenzione delle parole in libertà. Nelle opere precedenti, a un sostanziale disinteresse per il progressismo tecnologico corrispondeva un'attenzione ossessiva per la corporeità e un ricorso continuo all'allegoria, con effetti particolarmente grotteschi (soprattutto nel romanzo Mafarka le futuriste) nei quali si rilevano tracce di una concezione del mondo di sapore ancora medioevo-rinascimentale. Questa componente regressiva del futurismo marinettiano viene platealmente abbandonata a partire dal 1912, con Zang Tumb Tumb, salvo riaffiorare ciclicamente, come una corrente sotterranea, in altre fasi della sua carriera: nel 1922, ad esempio, con la pubblicazione de Gli indomabili (un’altra opera allegorica, ricca di reminiscenze letterarie). Quella del 1912 è una vera e propria frattura, che nel primo capitolo è indagata sia da un punto di vista storico (attraverso la documentazione epistolare e giornalistica vengono portate alla luce le tensioni che portarono gran parte dei poeti futuristi ad abbandonare il movimento proprio in quell'anno) che da un punto di vista linguistico: sono sottolineate le differenze sostanziali tra la produzione parolibera e quella precedente, e si arrischia anche una spiegazione psicologica della brusca svolta impressa da Marinetti al suo movimento. Nel secondo capitolo viene proposta un'analisi formale e contenutistica della ‘funzione grottesca’ nelle opere di Marinetti. Nel terzo capitolo un'analisi comparata delle incarnazioni della macchine ritratte nelle opere di Marinetti ci svela che quasi sempre in questo autore la macchina è associata al pensiero della morte e a una pulsione masochistica (dominante, quest'ultima, ne Gli indomabili); il che porta ad arrischiare l'ipotesi che l'esperienza futurista, e in particolare il futurismo parolibero posteriore al 1912, sia la rielaborazione di un trauma. Esso può essere interpretato metaforicamente come lo choc del giovane Marinetti, balzato in pochi anni dalle sabbie d'Alessandria d'Egitto alle brume industriali di Milano, ma anche come una reale esperienza traumatica (l'incidente automobilistico del 1908, “mitologizzato” nel primo manifesto, ma che in realtà fu vissuto dall'autore come esperienza realmente perturbante).
